Designed Multi-Point Hydraulic Transmission Controlling Circuit on Self-Propelled Forestry - Agricultural Machines

Abstract

Multihead machines have been invented and applied in Vietnam. However, those machines often use mechanical transmission system and only a few of them use one-point hydraulic transmission system. Mechanical transmission has some drawbacks of space, size, weight, etc., leading to the inefficiency of those machines. As a result, the practical demands have required us to research, analyze and make multi-point hydraulic transmission controlling circuit. This research will be the foundation for the next research and invention of controlling circuits and multi-point hydraulic transmission of self-operated machines that can be practically applied in agriculture and forest sectors in the future.
